Since i try to test ermanometry on many instruments only one test satisfy me fast full. Weekly chart of BTCUSD. Erman wrote in his book, that only daily should be used (as the highest timeframe used) but since February 2018 in case of BTC weekly chart is more accurate to get intresting turning points. The lower timeframe (i tried to test even 1h) the more mistakes we get. If You have some questions to the chart above, feel free simply to ask me;)
